what you are looking for is a machine from silicon graphics called an octane, the computer was designed to run alias wavefront, i found a set of books from when my dad used to work there years and years ago. most of the textures your looking for are referenced in these books, it seems like a few like cobble_stone were kept and other "skybox" style images were lost over time but your hunt is for something running Irix as an os
